García Sánchez, Raúl (author)Early design decisions have a significant influence in the final success of the project. One of the most important decisions is to determine the system architecture, as it highly impacts the performance of the system. System architecture optimization can be used to determine the best possible architectures through the formulation of an...master thesis 2024

Nikitin, Mikhail (author)With growing demand for air transportation, it is crucial to improve the efficiency of aircraft systems design. A key area of focus is the implementation of manufacturability considerations into the design process at early stages. This could be done by integrating manufacturability analysis modules into an MDAO workflow, however, each production...master thesis 2024

van der Werff, Daan (author)In the conceptual design phase, OEMs perform technology assessment to identify feasible solutions for their new aircraft. When the OEM is unable to assess a certain technology themselves, they consult Tier-1 suppliers to involve<br/>them in the design process. The suppliers have higher fidelity analysis tools that can help the OEM with their...master thesis 2023

Müller, Lukas (author)Aircraft design systems are frequently used to synthesize aircraft designs. However, it is inherently difficult to reconfigure these software systems to facilitate a broader range of design studies (e.g. optimization or sensitivity studies) and to address follow-up questions about the synthesized aircraft designs. This report presents an...master thesis 2023

Attili, Cristiano (author)One of the current trends in the aviation world is to work towards an increasingly more computer-aided approach to flying. Despite the improvements, limitations still inevitably exist in terms of power and storage capabilities in the aircraft avionics. To overcome this problem, different solutions have been proposed. A data-driven approach is...master thesis 2023

Valencia Ibañez, Santiago (author)System architecting is one of the first stages of the engineering problem-solving process. Pivotal decisions regarding the system's overall configuration are taken in this phase. Consequently, decision support tools like system architecture optimization are needed to effectively assess the architectural design space. However, system architecture...master thesis 2023

Exalto, Joaquin (author)Much like the oil crisis in the 1980s, the aviation industry is once again considering more environmentally sustainable propulsion options due to concerns around climate change. More fuel efficient propulsion methods form the pillar on which environmentally sustainable aviation can be built, since it is the propulsion system that emits harmful...master thesis 2023

Rein, Max (author)The increasing complexity of aeronautical systems and the prevailing focus to develop sustainable technological innovations for future aircraft configurations and technologies have emphasized a particular demand on advancing the Multidisciplinary Design Analysis and Optimization (MDAO) technique. MDAO addresses the complex synergy within...master thesis 2022

Kilkiş, San (author)Present Knowledge Based Engineering (KBE) applications do not facilitate collaborative processes due to lack of process formalization and orchestration capabilities, leading to ad-hoc solutions. This increases application development time, reduces re-usability, and increases the cognitive burden of users leading to decreased design efficiency....master thesis 2022

Bansal, Darpan (author)Considerations that decide producibility of a design are an important part of the design process, and must be included in the early design stages to ensure that these designs can be realised. Not including these considerations carries the risk of incurring additional costs and delays at later stages of product development because of design...master thesis 2022

Baliga, Adithya (author)Novel designs like the Flying-V, Prandtl-Plane and Blended Wing-Body show promise towards sustainable aviation. In the preliminary design phase, Sub-scale Flight Test (SFT) is a reliable method to get insight into the flight behavior of these designs. The effectiveness and value provided by SFT depends on the similitude between the SFT model and...master thesis 2022

de Priester, Costijn (author)This work introduces the Surrogate Advisory System (SAS), a Python package that aims to reduce the existing complexity when working with surrogate-based MDAO systems. SAS automates most of the steps for a CPACS-based MDAO workflow and drastically reduces required efforts to integrate surrogate models within MDAO systems. Key developments...master thesis 2022

Megill, Liam (author)The aviation industry continues to contribute to anthropogenic climate change. Recent studies have shown that the total radiative forcing from aviation is around three times higher than that from CO<sub>2</sub> alone. To account for the full effect of aviation, climate metrics are needed, which equate the environmental impact of various...master thesis 2022

van Manen, Bas (author)Requirement management is an important part of the design process. A perfectly feasible design can be useless if it does not meet the requirements imposed on the design. With the upcoming automation in the design process, requirement management can become even more complicated. How are requirements driving the design and how are these...master thesis 2022
